Yeah it does. Perhaps if he hadn't attended the weddiing at all? Which would then have attracted the attention of Kira, where he could then have said he can't be around them anymore. It's such a shame the plotline was handled in this way. If they'd just had a little more faith in themselves and let Odo become isolated, they could have perhaps thought up something further down the line. The missed potential is comparable to the mishap over Section 31 in Extreme Measures.
